从属连词用法:
从结构上说,英语连接词分两大类:并列连词和从属连词。
并列连词连接两个或两个以上地位平等的字、词组或分句。例如: (1) Air and water are indispensable to me. (2) She likes going out with friends or playing outdoor games. (3) Most workers have a good income, so they look very happy.
从属连词连接两个或两个以上的分句,形成复杂句中的从属分句。例如: (4) He said that he did not want to go . (5) Many things have happened since I last saw him. (6) You may come if you want to.
从属连词用来连接各种从句。 until(till)直到,在用until表达时间状语的句子中,主句中的动词是要十分小心去选择的。 如动词是持续行动词,它要用肯定句,如: I studied hard until 12 o'clock last night. 如果动词是瞬间截止性动词,则要用否定句,如: He didn't go to bed until his mother came back. 由since,for,by,before, 来引导的时间状语从句。 since 引导的时间状语是动作的开始时间,如: I have studied English since 1990. 而by引导的时间状语通常是动作的结束时间,如: I had learned 25 English songs by the end of last term.
· 从属连词: 这种连词是用以引导名词性从句定语从句和状语从句的,由从属连词所引导的句子叫从句,而含有从句的句子叫作复合句。
· 从属连词可分为三大类: 1、that (无词义,不做成分) if,whether (表达是否的意义,但不做句子成分) 2、连接代词:who,whom,whose,what,which,whatever, whoever, whichever(有词义,在句子中可作主语、表语、宾语) 3、连接副词:when,where,why,how,how many,how long,how far,however,whenever,wherever (有词义,作从句的状语)
